I’m Pretty Sure I Was Sexually Assaulted, But Was Unconscious The Whole Time.

this is my first time posting on reddit, so i apologize if this isn’t the right subreddit to ask this question. please direct me somewhere else where i can get clarifying legal advice about whether i should press charges about this or not.

Location: Idaho

2 nights ago, i (20F) was drinking with my friends, two who are men (20 & 25) and one who is a woman (20F). just to try to smooth this over as much as i can, things got out of hand with drinking (as they usually do with college students like myself) and i proceeded to black out. the next thing i noticed when i woke up my friend (20F) had woken me up in bed to my surprise saying “(My name), you need to know what the fuck happened last night.” i was immediately startled and taken aback, to which i looked down and realized my underwear my and shorts had been taken off and thrown on the ground.
i was in complete shock when she said she had found my friend (20M) in my room alone after she stepped out to take a phone call with her friend for about an hour. our doors in the dorms have an automatic lock, where you can only unlock the door from the inside and would need a key from the outside to get in. my friend (20F) was banging on the door, asking to get back inside. when she came in, all my other friends had left, except for my friend (20M) who was lying next to me in his boxers. i was undressed completely on the lower half, completely unconscious and passed out. my friend (20F) was in shock and horrified to see what she had saw. she continued to tell him to leave the room, and even walked him back to his dorm.
before she dropped him off, she had cracked my door with my yoga mat to ensure the door didn’t close and automatically lock. little to my friends knowledge, my friend (20M) didn’t actually go back to his room, but rather back up the stairs and navigated his way back into my room and closed the door again.
my friend (20F) was terrified and furious, banging on the door very loud and repeating to be let inside. my friend (20M) opened the door and he was fully clothed, but was telling my friend (20F) to “wait, stop just let me stay. give me a second…”, and things along that line.

today i got a forensic examination anonymously, and i have been told that i should report this to the police. but, i’m just so scared that i somehow encouraged the situation to happen, or that i allowed things to go on, and it would be my fault and the case would be dismissed.
does anyone know what route i should take about this and if i can press charges, even if i did encourage something when i was blacked out/not fully conscious in Idaho? please help, i don’t have anyone else to talk to about this other than my (20F) friend who is just as lost as me. i remember absolutely nothing other than one moment i was playing a drinking game, and the next i wake up with vaginal pain and discomfort with my lower half of my clothes off.
